STORAGE BUILDING.

Application led March 13, 1919. ,Serial No. 282,437.

l To" all whom t may concern ing.

Be it known that I, PAUL MANDEVILLE,

a citizen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new. and useful Improvements in Storage Buildings, of which the following is a specification, reference being had to the accompanying draw- My invention relates to buildings used for cold storage or pre-cooling purposes in which the interior ofthe buildin must be insulated as completely as possi le from the outside atmosphere, such for example as that shown and described in my pending application, Serial No.'273,788, filed January 2.9, 1919. As is well understood by those familiar with such buildings, it is of the utmost importance that the door or doors pf such buildings be so constructed as to provide adequate insulation around the doorway when they are closed, and be capableof being opened and closed easily and quickly. It is also important that the door be so constructed and arranged as to be movable coinpletely away from the doorway so that it will not interfere with the passage of loaded trucks. To provide a construction which meets the exacting conditions of such service is the object of my present invention, which object I accomplish as illustrated in the drawings and as hereinafter described` lVhat I regard as new will beset forth in the claims.

In the drawings which illustrate part of of the side of a warehouse showing the doorway and the door for closing the same,-

Fig. 1 is a partial front elevation showing the door closed. oij in what mayv be termed its operative position;

Fig. 2 is an enlarged vertical section on line 2 2 of Fig. 1;

Fig. 3 is a horizontal section on line 3-3 of Fig. 1; I

Fig. 4 is an enlarged partial sectional view on line 4 4 of Fig. 1; and

Fig. 5 is a greatly enlarged partial horizontal section of one of the casing boards of the doorway showing the construction of the insulatin strips.

Referring to the drawings,6 indicates the warehouse wall, and 7 the doorway thereof. 8 indicates a floor or platform outside the doorway. 9-'10 indicate vertically disposed casing boards at the sides of the doorway `7, and 11 indicates a horizontal casing board which extends over the doorway. 12 indicates insulating strips which are secured along both side margins of the casing boards 9-10, as sh'own in Figs. 3 and 4, and also along the lower margin of the casing board 11, as shown in Fig. 2, in suchmanner as to proJectbeyond the outer surfaces thereof, as shown in said lfigures. In Fig. 5 I have illustrated an improved form of insulating strip which prefer to use for this purpose, said strip being made of a canvas strip folded and refolded longitudinally to form a looped propecting portion 12, the folded strip being secured in position back of the said looped 'portion by retaining strips 13 screwed or otherwise suitably secured to the casing board or other part to which the insulating strip is attached. I thus provide a resilient insulating stripwhic'h encloses a dead air space so that it is a goodnon-conductor of heat and cold and wears well under severe conditions.

14 indicates an insulating door, which is mounted to slide into andout of position with respect to the doorway, and is hung on door hangers of any suitable type which will permit the door tov swingl to a slight extent toward and from the wall of the building. For this purpose I have shown it as being pivotally suspended from door hangers 15 running in a longitudinally disposed track 16 which extends over tlie doorway and for a suicient distance at one side thereof to permit the doorto be moved so as to completely expose the doorway. The track is inclined slightly so that as the door is moved away from the doorway it is lifted suiiciently to be clear of the floor. The door is, however, hung so that its lower margin is horizontal in order to permit it to bear closely on the floor when it is in operative position. (See Figures 1 and 2). In the construction illustrated the door is suspended from the hangers 15 by straps 17 which are connected by pivots 18 with overlapping straps 19-20 secured to the upper portion of the door, but any other suitable construction may be employed. As best shown in Fig. 2, the door is connected with the hangers at a point outside of its vtransverse center so thatthe door naturally tends to assume a position inclined to the vertical with its lower tion farther from the wall of the building than its upper portion. The purpose of this arrangement is to facilitate the sliding of the door linto and out of operative position, and

to preserve the insulating ai wear occasioned by thesllding of the door, as will more fully hereinafter appear. The' inner face of the door is a plain or flatsurface so that when it is in operative posltion overl the doorway it will bear against the-- projecting portions of the several insulating strips 12. At its lower side the door the outer side of the door adjacent to its lower edge and adapted to engage inclined blocks 2425, respectively, secured to the floor 8 approximately opposlte the sides of the doorway. The purpose of these blocks is to move the lower portion of the door 1nwardly into tight contact with the insulating strips 12 when-the door is moved 1nto operative position in front of the doorway. 26 indicates a plate in the form of a heavy plank which is secured to the wall of the building in position to form a stop for 'the door when-it reaches its operative posit1on. This stop 'plate is preferably set a short distance away'from the adjacent margin of the casing board 9, as shown at 27 in Fig.

4, to insure good Contact between the door and the strip 12. 28 indicates an approximately U-shaped bracket which is adapted to overlap a staple 29 carried by the door, so that by means of a padlock 30 passed through the overlapping portions of said members the door may be locked in its closed position. p

When the door is in its open or inoperative position, it is suspended from the higher portion of the track 16 so that its' lower margin is out of contact withl the floor 8,

and owing to the olf center position of theV hanger connections, it normally hangs so that its lower rtion stands away from the wall of the building, as has been explained. The inner faceof the door is therefore out of contact with the wall of the building and is far enough away therefrom so-that when it is slid toward its operative position it does not bear against the strips 12 around the doorway. `While in this inclined position the' door is slid edgewise until it arrives over the doorway, when the blocks 22-24 and 23-25 come into engagement respectively with each other and a slight further movement of the' door in the same direction accordingly forces the door over laterally into close contact with the. insulating strips 12, the door then assuming a vertical position. At this time the .insulating strip 12 which extends over the doorway reaaaoa provides insulation at the top, and the two insulating strips 12 at each side of the doorway cooperate with the door te V`form dead air spaces 31, shown in Fig. thus providstrip 12 carried bythe bottom piece' 21 Y' which then bears closely' for its entire length on the floor 8 but when the door is not in its operative position said strip is out of contact with the Hoor. In opening the door considerable force is required to loosen it from the blocks 24--25, but after it has been loosened its lower portion swings outwardly and it may then be slid along easily from in front of the doorway. Y set farther from the door than the block 25, as shown in Fig. 3, so that the block 23 can pass the block 24 to permit the door to be moved completely away from in front of the The block 24 is doorway. Asthe door moves easily after it has been disengaged from the blocks 24-25'it will be apparent that it can be opened and closed very quickly thereby facilitating the maintenance of the low temperature required in buildings of this character.

The door itself is constructed in a novel A composed of upper and lower rails 31-32 and stiles 33--34 secured together in the form of a rectangle. This frame is filled in with a mass of insulating. material 35 such as cork board or any other light rigid insulation. This insulation is also enclosed by sheets of felt 236-37, or other suitable insulating material, one of said sheets, as 37, being extended between the insulation 35 and the door frame, as shown in Fig. 2. 38-39 indicate vertically disposed matched strips of lumber which form the facing for the outer and inner sides of the door, as shown in Figs. 1 and 2. 0n the outside the door is preferably trimmed with a series of vertical strips 40-41 and horizontal strips 42-43--44, as shown in Fig. 1'. The door hanger straps 19-20 are secured to the facing strips 39, the vertical strips 40 and the upper rail 31 by bolts 45, as shown in Fig. 2, so that the suspension strains of the door aretaken up by said facing and vertical strips. I thus provide a very eective insulating door which may be made quite light so that it can be easily handled.
